«We saw no reason not to believe that if amyloid seeds entered the human brain, they would also cause amyloid pathology in the same way,» says Jucker.

The paper by Collinge and his colleagues has sparked a worldwide hunt for similar amyloid pathology in autopsied brains, and a small study published this January revealed a handful of related cases.

Taken together, our results demonstrate that the intraneuronal development of AD - like amyloid pathology includes a mixture of molecular species (Aβ, APP and CTFs) of which a considerable component is Aβ; and that the early presence of these species within neurons has deleterious effects in the CNS, even before the development of full - blown AD - like pathology.

Further to it, we have demonstrated that the early CNS amyloid pathology is reflected and can be monitored in the rat CSF.

It was thanks to this routine work that the cluster of unusual cases emerged of people who had clearly died of CJD, but who also had obvious signs of amyloid pathology in their grey matter and cerebral blood vessels.

However, with increasing age and advancing amyloid pathology, fear conditioning deficits severely progressed in homozygote animals (Figure 6d - f).

And they can not entirely rule out the possibility that the treatments themselves — or the patients» original medical conditions — caused the amyloid pathology.

«This Image of the Year study begins to address that fundamental question and leads to the next investigational study to determine the relative contributions of tau and amyloid pathology to neuronal dysfunction.

The examination of the amyloid pathology with super-resolution microscopy permitted us to further reveal a clear separation of the subcellular location of Aβ - immunoreactivity from that of APP / CTFs.

Note the progression of auditory and contextual fear conditioning deficits as the amyloid pathology advanced from pre - to post-plaque stages.

A role for Aβ - mediated toxicity is further supported by the fact that cognitive deficits progressed according with the incremental accumulation of the amyloid pathology, in particular, increased levels of soluble Aβ42 (Figure 8a).
